Get matched with top glaziers in Boulder, CO

"Keith was wonderful about working with me, re-ordering what I thought I was going to get in the first place and charging me fairly for the difference in material. The only challenge in the process was with the trim painters who came at odd times (Thanksgiving morning!)and required the doors to remain open for several hours - understandable but tough in the winter with babies in the house! My overall experience was exceptional. I highly recommend the whole GS Construction team and would definitely use them again should the need arise."

"I am very skeptical on door to door sales but they did everything excellent. Everything was very smooth and I didn't feel pressured at all to get my windows fixed. They worked very well on financing. They did our install in one day and was very clean about it. Everyone did a very good job in our project for our windows."

"Keith worked with me for about 3 months before I decided the final project. Keith was very professional and patient. He gave 3 estimates for which to choose from. He even hired a designer to help with the colors and placement of the panels. Work was started on time and it looks wonderful. I would highly recommend GS Exterior Experts."

"We recently had an egress window installed and couldn’t be happier with the experience. The team was professional, efficient, and paid great attention to detail from start to finish. They kept the work area clean and made sure everything was done to a high standard. The window looks fantastic and has completely transformed the space. We’re so glad we chose them for this project and would highly recommend them to anyone looking for quality work and great service."

"The project included windows and doors replacement, exterior trim, and rain gutter installation. Project was done efficiently and expeditiously. Contractors for all work were very hard working and conscientious, concerned to address my needs and questions. Project manager AJ Smith saw an issue that didn’t meet his standards and immediately and personally rectified it. Very pleased with the end result."

"We had DMD intall a bay window for us in the 80's and were so pleased with the results. Needing to place windows and doors, I was delighted to see they were still here. Again, Bill was most accommodating and and responded to questions in a timely manner. Chad, Alex and Kevin came to demo and replace 2 sliding glass doors and several windows. Their work ethic and teamwork was unbelievable. I HIGHLY recommend DMD for any work you may want done."

"I cannot praise this companies work enough. They literally check all the boxes when it comes to a home renovation professional. Clear and timely communication, started and completed the job when promised, very neat and tidy, and did work above and beyond expectations. I would highly recommend them for a egress window install any other services they may provide. As a bonus, their work added $10k to our homes value."

"I am super impressed with the quality and warranty. Definitely a step up from the builder grade windows we currently have and that are available at the big box stores. And the warranty is a lifetime warranty on all parts and glass and is transferable. I worked with Joe. He was very friendly, and knowledgeable."

"It went great! Paulo was the only contractor to answer his phone when i was trying to reach a contractor. He showed up right away and looked at everything and told me he could do some investigating to see what was causing the bulging. He did exactly what he told me he would do and only charged me $150. HIGHLY RECOMMEND!"

"Excellent service and a great price for a quality product. Owner was very knowledgeable of the product and helped me choose the right grate"
